I think most of those microsample sites date back to the stone age where there were a lot fewer colours available to use on the web. You'd probably do better using one of those sites where you select any one of the 16,777,216 possible colours and have it tell you what other colours are most appropriate to use with the one you selected. With a chart of only 504 colours you would choose one and all the suitable colours to use with it will not be on the chart making it rather useless.

felgall, I would recommend people use a color schemer program, they allow you to build up color palettes from the full amount of colors available. If anyone wants to know, I use the commercial product Color Schemer Studio and it is probably the single most useful utility I have in my web design kit.

It does look like an extremely primitive version of the sort of thing I was talking about. There are free online versions that are far far far more sophisticated than that one.There were several such sites mentioned in a recent book on web design (If I could only remember which one it was -I have several piles of computer books stacked around the place at the moment waiting to be properly put away when I can find somewhere to put them all).

I like colorschemedesigner thanks.
I've used colorsontheweb(dot)com/colorwizard.asp - it shows the hex value for all colors on the palette, and each rgb has a slider. There's also a WCAG contrast anaylzer.
